To all whom it may concern:

Be it known that I, LOUIS H. SCOTT, a citizen of the United States,residing at Buda, in the county of Bureau and State of Illinois, haveinvented a new and useful Improvement in Post-Molds, of which thefollowing is a specification.

My objectis to provide a simple construction of mold of the characterstated which may be manufactured at relatively low cost, and be easilyand quickly operated to mold posts without subjecting the molded mate- Irial to jarring actions tending to impair the integrity of the moldedpost.

My invention is illustrated in the accompanying drawing, in which-Figure 1 is a View in side elevation of a mold constructed in accordancewith my invention, the mold in this view being shown in uprightposition, viz., the position it occupies while being filled withconcrete. Fig. 2 is a view like Fig. 1 showing the mold inverted, inwhich position the molded post is freed from the mold. Fig. 3 is anenlarged section taken at the line 3 on Fig. 1 and viewed in thedirection of the arrow; and Fig. 4, a perspective view of one of the twosimilar end bearing-heads with which the mold is equipped and on whichit is adapted to be turned for inverting it.

The mold` generally stated, comprises a trough 5 equipped at itsopposite ends with bearing-heads G at which the mold rests on theground, or floor, as the case may be, and at which it is moved fromupright to inverted position, as hereinafter explained. The heads 6 areformed of plates 7 of general circular-shape in contour affordingopposed arc-shaped edges 8, with straight edged portions 9 and 10 atopposite edges of the heads, as illustrated in Fig. 4l. The

. heads 6 at their curved edges 8 and lower straight edges 10 arepreferably provided with inwardly-extending flanges 11 and 12 of a shapecorresponding with the edges of the heads from which they extend, asillustrated in Fig. 1, whereby relatively broad bearing-surfaces for theheads to rest on the ground, or floor, are provided. The upper portionsof the heads on their inner faces are provided with brackets 13 spacedapart horizontally and formed with shoulders 14. affording seats for thetrough 5 as hereinafter described, and with depending portions 15, thebrackets in the constructions shown being integrally connected with theflanges 11 at their upper ends. The trough 5 is formed of sheet-metalbent transversely into the cross-sectional shape necessary for forming apost of the desired contour, the trough in the construction shown beingrounded at its lower end to form a post curved on one side. The upperedges of the trough are deflected outwardly to formhorizontally-extending flanges 16 which seat at their extremities uponthe shoulders 14 of the brackets 13 and to which they are riveted, thetrough at its ends ext-ending into the space between the dependingportions 15 of the brackets to which it is rigidly secured.

The filling position of the mold is that illustrated in Fig. 1, in whichthe heads 6 rest on the ground, or floor, at their flanges 12, and thetrough 5 is in upright position. To make a post, the concrete is filledinto the trough and tamped by any suitable tool (not shown) to thedesired density, then leveled on' and corrugations formed in its upperface if desired, whereupon a pallet 17, which be a board, is seated onthe top of the molded material and the upper surfaces of thetrough-flanges 16. The pallet should then be clamped in place, by anysuitable means, such for instance as those illustrated, which comprise aplurality of clamps 18 secured at intervals to the flanges 16 at theopposite sides of the trough, and each preferably formed of a head 19secured to the underside of the flange 16, a lever 2O pivoted at one endto the head 19, as indicated at 21, and a jaw 22 pivoted at its lowerend to the lever 20 between the ends of the latter and adapted to engagewith the upper surface of the pallet 17 at its adjacent marginaledge-portion and be held thereto against accidental displacement whenthe lever 20 connected therewith is swung to the position illustrated ofthe one on the left-hand side of Fig. 3. After the pallet has beenclamped in position as described, the molded post is ready to be freedfrom the mold and this is effected by turning the mold over to theposition illustrated in Fig. 2, the mold in this operation turning 22,whereby when the mold is inverted its weight does not rest upon thejaws. After inverting the inold as described, the clamps 18 aredisengaged from the pallet 17 by swinging the levers 20 outwardly anddownwardly, whereupon the niold thus disconnected from the .pallet maybe lifted from the pallet 17 by the levers 2O to tree the molded post,which latter is allowed to rest on the pallet 17 until it has become setsulliciently to permit it to be handled.

Itwill be noted from the foregoing that the removal of the molded postfrom the mold is effected without requiring the post t-o be lifted, themold simply turning over on the curved flanges 11 of the heads, toinverted position and freeing itself of its contents, without subjectingthem to jarring brackets secured on the inner faces of the 25 heads toextend transversely otlv such faces and provided with shoulderedportions torniing seats, and a trough connecting the heads together 'andprovided with out-A wardly-extending flanges seating at their 30 endsupon and secured to said shouldered portions ot' the brackets.
